Air Quality Monitoring System: A Comprehensive Overview of an advanced Air Quality monitoring system using Arduino

Abstract

This study focuses on enhancing sensor technology and shrinking the size of sensors utilized in monitoring the quality of atmospheric air. With the escalating concerns over air pollution due to factors such as increased vehicular traffic, industrialization, and urbanization, there is a pressing need for effective monitoring solutions. The innovation at the core of this study involves implementing IoT technology via a Wi-Fi module interfaced with a gas sensor, facilitated by an Arduino UNO microcontroller. Specifically, the study proposes the utilization of the MQ 135 Air Quality Monitoring Gas Sensor for measuring air pollutant concentrations. The setup primarily comprises an Arduino UNO board integrated with an ESP8266 module for IoT connectivity. This IoT which depends on Air Quality Monitoring System is designed to monitor the air quality via a web server using the ESP8266 Wi-Fi device. Additionally, it is equipped to trigger an alarm when air quality deteriorates to a certain level, indicating the presence of harmful gases like CO2. The system displays air quality depends in Parts Per Million categorizing it into Fresh Air, Poor Air, or Danger Air, allowing users to monitor the air condition status effectively.
